ATT-290F-20-SMA-02

Attenuators Overview

The ATT-290F-20-SMA-02 is a fixed coaxial attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 18 GHz. The device features SMA female connectors on both ends and supports a maximum power rating of 2 Watts. Constructed for reliability, it operates within a temperature range of -65°C to +125°C.

Attenuators Feature Summary

• Provides precise 20 dB signal attenuation across a wide bandwidth up to 18 GHz.
• Features SMA female-to-female connector interface for direct inline integration.
• Rated for 2W continuous wave power handling in a robust coaxial design.

Attenuators Applications

• RF test and measurement equipment requiring stable signal reduction.
• Telecommunications systems operating within the specified frequency range.
• Aerospace and defense electronic assemblies needing high-reliability components.

Attenuators Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required impedance and connector gender. Confirm RoHS compliance status and REACH SVHC declarations prior to procurement. Cross-reference manufacturer part numbers with distributor codes to avoid ordering errors due to similar series naming conventions.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation value is required at frequencies up to 18 GHz. Ensure the system power levels do not exceed the 2W rating. Verify that SMA female connectors match the existing circuit board or cable assembly interfaces. Consider thermal management capabilities given the operational temperature range limits.

Attenuators Part Context

This model belongs to the ATT-290F series of connectorized attenuators designed for high-frequency applications. It complements other variants in the lineup offering different attenuation values such as 2 dB, 6 dB, and 30 dB, all sharing similar form factors and electrical performance characteristics suitable for demanding RF environments.

Attenuators Replacement Considerations

Direct substitutes include ATT-290F-20-SMA and ATT-0290-20-SMA-02, which share identical electrical specifications and mechanical dimensions. Verify connector polarity and mounting style before substitution to ensure seamless integration into existing designs without modification.
